I have seemed to run into some bug or a dead end. After popping the cocoon open, the mouse cursor simply disappears and I can't interact with anything, the music still plays and menu is accessible, but the game itself can't be played. Tried it a couple of times, but since there's no save game functionality, I kind of gave up on further experimenting.
It was really fun and enjoyable up to that point with quirky characters, great voices and logical puzzles.
